Do the (quality of) DC cables matter?

[David A]

Yes, i still do too ;-)

Here you have options: https://ghentaudio.com/part/list-dc.html

Also, Keces from which i own a lps is selling very expensive ones: https://www.kempelektroniksshop.nl/m-way...-dacs.html

But yeah, is this something you are able to hear, compared to the standard cheapo black cables...?

The cable in that link is listed as an M-Way cable, not a Keces cable. Kemp Electronics sell Keces but those cables are not listed as Keces products on their page for Keces products and it's Kemp Electronics, not Keces, who are selling them.

I checked your link because I use a Keces LPS and I too have wondered about other DC cables so I wanted to see what price Keces cables were selling for, only to find that the cables you were referring to aren't from Keces.
